05 WW I Patented July 10, 1934 UNITED STATES RUMBLE SEAT ATTACHMENT FOR TRICYCLES Gerald G. OConnor, Cleveland, Ohio Application October 4,

6 Claims,

The invention aims to provide an exceptionally simple and inexpensive, and an easily attached, convenient and generally desirable rumble seat attachment for a childs tricycle, and in carrying out this end, further objects are to make novel provision for resiliently supporting the seat, to provide unique seat-supporting plates formed of sheet metal yet sufiiciently rigid and durable to fulfill the desired purpose, and to provide a construction which may readily be attached to different makes of tricycles.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accom- 'plished by reference to the accompanying draw- Fig. 1 is a perspective view showing the attachment connected with a tricycle.

. Fig. 2 is a perspective view showing one of the seat-supporting plates and means for yieldably mounting the same.

A preferred construction has been shown and will be specifically described, with the understanding however, that variations may be made within the scope of the invention as claimed.

Two clamps 5 are provided for engagement with the rear axle 6 of a tricycle, said clamps being provided with upstanding rigid pins '7. Coiled compression springs 8 surround the lower portions of these pins, and short tubular guides 9 on the lower ends of two laterally spaced supporting plates 10 are slidable upon the upper portions of said pins, washers 11 being preferably interposed between said springs and said tubular guides 9. Each plate 10 is of triangular form, being provided with downwardly converging front and rear edges 12 and 13 respectively and with a substantially horizontal seat-supporting upper edge 14. All of these edges are provided with laterally bent reinforcing flanges, said flanges being denoted at 12', 13 and 14 respectively. The lower ends of the front and rear flanges 12 and 13 are transversely curved as denoted at 15 and they co-act with the adjacent lower end portion of the plate 10 in forming the tubular guide 9. A single piece of sheet metal may thus be used for easily and inexpensively constructing each of the seat-supporting plates 10, and it will be observed that these plates are yieldably supported by the springs 8, said tubular guides 9 being slidable upon the pins 7.

A horizontal seat 16 is secured by bolts, screws or the like 17' upon the seat rests or flanges 14, said seat preferably having a back 18, sides 18',

. 'and a safety strap 19. The back and sides may 1933, Serial No. 692,174

well be formed from sheet metal having a wirereinforced bead 20, whose reinforcing wire 21, is exposed at the upper front portions of the sides 18, forming loops for connecting the ends of the safety strap 19.

Two rigid hangers 22 are secured to and project downwardly from the front portion of the seat 16, the lower ends of said hangers being provided with a foot-board 23, which extends substantially between the lower ends of the seatsupporting plates 10 but is of course forwardly offset sufficiently therefrom to enable the occupant of the seat to comfortably rest his feet.

Above the ends of the foot-rest 23 I provide two tie chains 24, whose rear ends are connected with the upper portions of the plates 10, the front ends of said tie chains being provided with clamps 25 for securing them to the rear fork 26 of the tricycle. Preferably, the tie chains 24 include coiled tension springs 27 whose front ends are directly connected with the clamps 25 while their rear ends are adjustably hooked into links of the chains. The rear ends of these chains are preferably connected with the plates 10 by providing the latter with hooks 28. The tie chains and their springs are instrumental in permitting the connection of the attachment with different makes of tricycles, the springs 2'7 assist in yieldably mounting the seat for comfort, and moreover the two tie chains, being disposed over the ends of the footrest 23, form guards to prevent the occupant of the seat 16, from accidentally engaging his feet or legs with the rear wheels of the tricycle.

The attachment is light, may be easily attached to the tricycle, and will comfortably support a small child, so that a larger child riding the tricycle may furnish pleasure for both.

I claim:

1. A rumble seat attachment for a tricycle, comprising two clamps to surround the rear axle of the tricycle, two laterally spaced seat supports rising from said clamps respectively and. having horizontal seat rests at their upper ends, a seat secured upon said seat rests, a foot rest extending between the lower ends of said seat supports, mounting means for said foot rest, ties above the ends of said foot rest and connected at their rear ends with said seat supports, and means on the front ends of said ties for securing them to the rear fork of the tricycle.

2. A rumble seat attachment for a tricycle, comprising two clamps to surround the rear axle of the tricycle, two laterally spaced seat supports rising from said clamps respectively and having horizontal seat rests at their upper ends, a seat secured upon said seat rests, a foot rest below said seat, hangers secured to said foot rest and to said seat, ties above the ends of said foot rest and connected at their rear ends with said seat supports, and means on the front ends of said ties for securing them to the rear fork of the tricycle.

3. A rumble seat attachment for a tricycle, comprising two clamps to surround the rear axle of the tricycle, two laterally spaced seat supports rising from said clamps respectively, resilient means supporting said seat supports upon said clamps, a seat mounted upon the upper ends of said seat supports, ties connected at their rear ends with said seat supports, said ties having elastic portions, and means for connecting the front ends of said ties with the frame of a tricycle.

4. A rumble seat attachment for a tricycle, comprising two olamps to surround the rear axle of the tricycle, said clamps having upstanding pins, coiled compression springs surrounding the lower portions of said pins, two laterally spaced seat supports having tubular lower ends slidably surrounding the upper portions of said pins and resting on said springs, a seat secured upon said seat supports, ties connected at their rear ends with the upper portions of said seat supports, and means for connecting the front ends of said ties with the rear fork of the tricycle.

5. A rumble seat attachment for a tricycle, comprising two clamps to surround the rear axle of the tricycle, said clamps having upstanding pins, coiled compression springs surrounding the lower portions of said pins, two laterally spaced sheet metal seat supporting plates having downwardly converging front and rear edges and substantially horizontal upper edges all provided with lateral flanges, the lower ends of said plates being provided with short vertical tubular portions slidable upon the upper portions of said pins, a seat secured upon the upper flanges of said plates, and bracing means for said plates having means for connection with the tricycle frame.

6. In a rumble seat attachment, a vertical sheet metal seat supporting plate having downwardly converging front and rear edges and a substantially horizontal seat-supporting upper edge, said edges having laterally bent reinforcing flanges, the lower ends of the front and rear flanges being transversely curved and co-acting with the lower end of the plate in forming a short vertical tube, for the purpose set forth.
